Abstract: Disclosed is a method for fabricating a color filter for a transflective liquid crystal display device inexpensively in which desired color purities, brightnesses, and color tones are obtained for reflective display and transmissive display. A color filter for a liquid crystal display device includes pixels of a plurality of colors (8B,8G,8R), each pixel of at least one color including a transmissive area (7) and a reflective area (6). The pixel of at least one color includes a plurality of laminated color layers (4,5). The uppermost color layer in the pixel including the plurality of laminated color layers is composed of a photosensitive color resist (5). In the reflective area of the pixel including the plurality of laminated color layers, a transparent resin layer (3) is disposed between a substrate and the color layer portion.
